Abstract (en)

[origin: EP2801929A1] Touchscreen controllers and associated electronic devices are described which prevent eavesdropping of touchscreen activity. In one aspect, the present disclosure describes a touchscreen controller that includes a touch input interface for connecting to a touch-sensitive overlay of a touchscreen display and a touch output interface. The touch output interface provides an output in dependence on touch input received via the touch input interface. The touchscreen controller further includes an orientation sensor control output interface for connecting to one or more orientation sensors and an embedded processor coupled with the touch input interface, the touch output interface and the orientation sensor control output interface. The embedded processor is configured to generate an interrupt output signal for output on the orientation sensor control output interface. The interrupt output signal is configured to deactivate the orientation sensor for at least a period of time when the touch-sensitive overlay is activated with touch input.
